I do men's hair care as a day job. I actually give a really incredible hair cut if I do say so myself.
Would you pay for a fantasy hair cut? The haircut generally takes 30 mins in addition to whatever amount of time you would like to have to, well, you know... whatever.
I knew a woman out in San Diego a few years ago that did this, with FBSM or whatever she felt like at the time (case of YMMV) after the cut. She was EXTREMELY popular with the guys.
